DNS (Domain Name System) is a hierarchial, decentralized naming system for computers and resources connected on networks such as the Internet.
DNS is used for a variety of purposes. For example, when you type in "google.com" in your browser, your browser uses the DNS protocol to locate the corresponding IP address for "google.com". Then, it sends data to the server located at that IP address.
This tool helps you look up the DNS records associated with a domain name. Specifically, it retrieves the following types of records:
A records (used to specify IPv4 addresses associated with a domain name).
AAAA records (used to specify IPv6 addresses associated with a domain name).
